背景#
最近有一个需求，需要手动的去缓存cookie，然后启动APP的时候设置缓存过的cookie，项目网络框架用的是Afnetworking。
解决方案#
翻了下Afnetworking的issue，发现了作者对于cookie的解释
Afnetworking没有对Cookie做过处理
使用NSHTTPCookieStorage即可实现cookie的管理。上代码！
存cookie
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:url]];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:cookies];
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:data forKey:@"cookie"];设置cookie
NSData *cookiesdata = [[NSUserDefaults standardUserDefaults] objectForKey:@"m3cookie"];
if([cookiesdata length]) {
NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData:cookiesdata];
NSHTTPCookie *cookie;
for (cookie in cookies) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
}
}清理cookie
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies]) {
[storage deleteCookie:cookie];
